PrimaKlima PK150/160WHSPEC-THC Whisperblower – Quiet EC duct fan with climate control

The PrimaKlima PK150/160-WHSPEC-THC Whisperblower is a state-of-the-art, latest-generation duct fan, specially developed for use in grow boxes and indoor grow rooms. With its integrated control for temperature, humidity and speed, it enables precise climate regulation and ensures optimal conditions throughout the entire plant cycle.

At the heart of the Whisperblower is a powerful EC motor from ebm-papst, renowned for its high efficiency and exceptionally quiet operation. The newly developed airflow design generates higher pressure whilst consuming the same amount of energy, whilst simultaneously reducing noise levels.

With an airflow of up to 1400 m³/h, this model is ideal for big-sized grow boxes. The intelligent control system automatically adjusts the output to current climate conditions, ensuring stable temperature and humidity levels.

The aerodynamically optimised housing made of flame-retardant polyamide (nylon) is particularly robust and durable. At the same time, it helps to reduce noise and reliably protects the technology during continuous operation.

The integrated control system eliminates the need for external controllers – simply plug it in and get started straight away. The Whisperblower is therefore an ideal solution for all growers who value quiet operation, maximum efficiency and precise climate control.
